Murray was convicted of administering the propofol dose that killed Jackson in 2009 and he has spent the past two years behind bars. He was released earlier this month.

And after the medic revealed in a recent interview that he and his former boss would joke about Rowe’s looks, the former nurse, who is the mother of two of the late pop star’s children, has hit back.

She tells TMZ.com that Murray should watch what he says and look out, because within 18 months “a Jackson fan will shoot him dead, and I’d buy the bullet. I wouldn’t shoot him but I’d buy the bullet.”

Commenting on Murray’s remarks about her looks, she adds, “If I had a dog as ugly as him, I’d shave its a—, make it walk backwards and put a wig on it… At least I can breed (Rowe raises horses). He can’t even write prescriptions anymore.”
